Numerous new wildfires across the region; Lyons Ferry fire pouring smoke into Spokane

Lightning and New Wildfires

Numerous new wildfires have been ignited by lightning in the last few days, particularly across eastern Oregon and Washington where fuel (vegetation) conditions are very dry and receptive to fire. While thunderstorm chances are now diminishing, additional new fires may continue to emerge in the days ahead as warm, dry weather continues and intensifies into next week.

The largest and most active fires in Washington right now appear to be the Lyons Ferry fire (~30,000 acres), the Royal Lake fire (~12,000 acres), and the Kaiser Canyon fire (~2,200 acres). Keep in mind that, with the rapidly evolving situation, acreage numbers may not be fully accurate on these incidents.

Smoke and Air Quality

Eastern Washington woke up to widespread smoke, with the Spokane area in particular getting hammered by smoke from the Lyons Ferry fire. Air quality readings in Spokane have been VERY UNHEALTHY to even HAZARDOUS at times Friday morning.

The air quality index at Liberty Lake (Spokane metro) monitoring station has climbed into HAZARDOUS Friday morning. Data via WA Dept. of Ecology.

As a result, Air Quality Alerts have been issued from now through at least Sunday morning for Spokane, Adams, Whitman, and Lincoln counties. Alerts could be expanded to other areas as the smoke situation evolves. As a reminder, the blog has multiple resources linked on how you can stay safe during periods of wildfire smoke.

Looking Ahead

Through the weekend, wind patterns favor onshore flow and south or southwest winds across eastern Washington. While the air quality in western WA and the Cascades will remain GOOD because of this onshore flow from the Pacific Ocean, areas to the north and east of existing and emerging incidents in eastern Washington and Oregon will experience continued periods of smoke. 

Exact smoke concentrations and locations of worst smoke are difficult to predict with confidence because of the rapidly evolving wildfire situation, not just in Washington but because of the dynamic fire situation in eastern Oregon. If eastern Oregon fires continue to grow, smoke impacts could deteriorate further in south-central and southeastern WA (Tri-Cities, Walla Walla, Pullman). 

Fire weather conditions will also remain elevated into next week, and firefighting resources are beginning to get stretched thin, which could lead to additional fire growth on active incidents. The bottom line: stay tuned to your local air quality by visiting fire.airnow.gov -- and we will post another update on Monday. 

Turner Hill fire in North Idaho smoking out Spokane this morning

A fast moving fire started last night in the Turner Hill area, north of Sandpoint. Low mixing heights and a direct wind flow brought smoke through Sandpoint and into Spokane early this morning. Several monitors show Unhealthy NowCast AQI values for several hours. The weather system passing over the region won't help with mixing heights, but changing winds and precipitation should limit the duration of smoke in the Spokane area.

The Turner Hill fire is being managed by the Idaho Department of Lands and North Bench Fire District, with over 20 people actively working the fire last night. There was also a brush fire on an I-90 ramp this morning, which contributed a little to the smoke in Spokane this morning.

PM2.5 in north Idaho and Spokane area (8 am, Thursday July 16)

Lots of rain and thunderstorms are actively moving over northwest Washington and northeast Oregon today. Eastern Washington precipitation amounts will be more sporadic. Windy and dry conditions are anticipated for the Columbia Gorge and Cascade gaps of eastern Washington but the humidity levels will surge during the evening. However, a warming and drying trend will kick back in regionally this weekend.

Many lightning strikes are occurring across the region, so new fire ignitions are likely to be discovered over the next few days. Stay tuned for changing conditions and we'll post updates as needed. 

Fire Weather Ramps Up This Week!

Fire Weather This Week

Hot and dry conditions return to the inland Pacific NW today.  Tuesday and Wednesday will get even hotter, and dry thunderstorms are expected east of the Cascades, posing lightning ignition risks.  There may be some precipitation in areas, but fire weather will remain elevated.  We expect slight cooling on Thursday but fire danger will remain high as we approach a drier and hotter weekend.

Fires in Oregon

The East Evans Creek fire in southwest Oregon, north of Medford, has been producing significant smoke the past few days, with large plumes seen in satellite imagery.  The fire has burned nearly 4,000 acres but there has been a very large firefighter response, with over 1,000 people working the fire, actively protecting homes, and using aircraft to drop both fire retardant and water.  

Other wildfires of note (Anthony, Salmon, and Olive Butte) are clustered around the North Fork John Day Wilderness Area in northeast Oregon.  Incident management teams are working hard on these fires but more activity is expected this week.

Brunswick Complex in BC

The Brunswick Complex in BC received small amounts of precipitation over the weekend, which helped limit activity when coupled with the cooler temperatures.  Forest fuels remain dry and warm and dry weather will build early this week, but some precipitation may materialize on Thursday night.

Smoke Aloft This Morning

Fire in the Northwest Territories are producing copious amounts of smoke, with bands aloft seen as far south as Oregon in satellite imagery this morning.  This isn't a concern for our region, and there is no evidence of smoke mixing down to the surface.

Wildfire Complex in British Columbia growing quickly

Brunswick Complex

The Brunswick Creek wildfire started on July 2 near Boston Bar, BC, and quickly took off in steep terrain under hot, dry conditions. Strong winds led to additional nearby fires, including the Ainslie Creek fire which has grown even more.  Together, the Brunswick Complex fires along the Fraser Canyon have burned over 30,000 acres, prompting many evacuations and emergency response in the area.  

Whatcom county was moderately impacted early in the week, and some smoke was possible in Northeast Washington today, but there probably won't be noticeable impacts this weekend.  We expect the fires to continue burning, so Northern Washington will see intermittent smoke impacts throughout the summer.  Wind flow in the near term will help keep most of the smoke in Canada, but parts of Northern Washington will eventually see Canadian smoke.

New Wildfires in Oregon

Lightning on July 7 ignited new fires in Eastern Oregon.  Currently smoke plumes can be seen in satellite imagery from the Salmon and Greenhorn fires as well as the Anthony Fire.  While we don't expect any impacts in Washington yet, it's possible these fires could grow and eventually impact Southeastern Washington later this summer.

Fire Weather Watch in Central Washington (Saturday)

The National Weather Service in Spokane has issued a Fire Weather Watch on Saturday due to expected dry windy conditions in Central Washington (e.g. Colville Reservation, Okanogan Valley, and Waterville Plateau).  Rapid fire spread is likely so residents should avoid activity that could spark new wildfires. 

Fuels Drying Out

Fire risk will be moderate in the near-term but with higher danger in windy areas. Very dry vegetation means any new or existing fires could spread quickly and be hard to control. Fire potential is expected to rise steadily starting next week, and there is also the potential for more thunderstorms and lightning ignitions.

Celebrate safely this 4th of July

As we head into the holiday weekend, air quality across the state is currently good. Let's help keep it that way by exercising extreme caution with fireworks. Fireworks inject smoke into the atmosphere and are a leading cause of new fire starts around the 4th of July. A recent study found that between 1992 and 2012, the most common day for human-started fires was July 4, with over 7,000 fires starting on that day over the 20 year period (that's 388 fires per year just on one day!)

With warmer and drier weather expected Friday through the weekend and into next week, fire danger will begin to rise. While we still expect generally good air quality statewide, smoke impacts may occur near any new fire starts and in the immediate vicinity of firework activity. 

Fireworks and Air Quality

Fireworks produce dense smoke made up of fine particle pollution and a mix of toxic metals and chemicals. Air quality monitors across the state consistently register elevated PM2.5 concentrations on July 4 and 5. PM2.5 concentrations typically increase rapidly after nightfall on July 4, peak before midnight, and gradually return to normal by the morning of July 5. In communities closest to celebrations, AQI levels can reach the Unhealthy range.  Overcast weather conditions in Western Washington could allow smoke to linger throughout the day, as weak onshore flow and limited vertical mixing is expected.

Be Safe and Help Prevent Wildland Fires:

• Consider attending a public fireworks display rather than lighting fireworks at home.   
• Fireworks are illegal on forest lands.
• Follow all local fireworks rules and restrictions.  Check with local officials for your area.
• Where legal, ignite fireworks on a flat surface away from houses and dry vegetation.
• Keep a bucket of water or garden hose nearby to extinguish fireworks after use.
